Difference Between NSOutlineView and NSTableView

Question

Tell me the difference between NSOutlineView and view based NSTableview as I know view based table view may not contain tree controller and NSOutlineView can have tree controller object

is it true or wrong

Answer 1

Apple says it best:

NSOutlineView is a subclass of NSTableView that lets the user expand or collapse rows that contain hierarchical data. As in a table view, an outline view displays data for a set of related items, with rows representing individual items and columns representing the attributes of those items. Unlike a table view, items in an outline view are not in a flat list, but rather may be organized in a hierarchy, like files and folders on a hard drive, or managers and employees in an organization.

So, yes, what you say is true.
